IMPROVEMENT IN WATER-ELEVATORS.

TO ALL WHOM IT MAY CONCERN: y Y v Be it knomnlthat we, JOHN B. BICKELand YTH'LODOBE SCHOLZE, of the counties of Elkhart and Steuben, in theState of Indiana, have invented a new and useful Improvement inWater-Elevators; andwedo hereby declare that the following is a full,clear, and exact description of the constructionand operation of thesame, reference being had to the `accompanying drawings, making a partof this specification, in which- Figure 1 is a side elevation of ourimproved water-elevator. i

Figure 2, Va front View of same.

Like letters in both figures oi' the drawings indicate like parts.

Our improvement has reference to the peculiar construction of an armprojecting from the crank at vthe 'point of its attachment to the shaft,operating Yin combination with a peculiarly constructedV pawl, the armvreleasing the pawl from a circular ratchet tooth-plate, andlsimultaneousl)7 acting as a brake on the face side of the plate on thedescent of the bucket. The circular ratchet tooth-plate, constructedwith a suitable number of'pcrforations, equal distance. apart, aroundnear the periphery of the sante, for the introduction-of a pin on thecrank in such ones as maybe desired for revolvingr the plate, and thusturn the windlass to elevate the bucket, may be deemed an essentialfeature of our improvement.

The construction and operation of the parts herein referred toarede'scribed as follows: 'A is the circular ratchet toothplate,provided with perforations a in the manner and for the purpose aboveremarked.v It is supported on a small shaft sumciently loose to admit ofan easy rotation thereon. The shaft is secured by a suitable bearing, I,on the cross-piece b of the framing around the well. TheA plate is alsoprovided with a circular recess on the back of it, having teeth invertedfrom the'periphery thereof to the axis of motion.` Located in the recess`and meshing into theI teeth therein are the teeth of a pinion-wheel onthe end of the windlass B, 1which latter is secured by suitable bearingson the cross-pieces of the framing. This completes the gearing apparatusfor raising and lowering the bucket, with the exception of the crank andpawl, which will now be described. C represents the`erank on the shaftof the ratchet tooth-plate. The shaft being constructed with a nut, c,on the end of it, is introduced through the hole of the crank and thatofthe plate, and thence .screwed into the bearing by a wrench applied tothe nut. This brings the crank against the side ofthe plate, where itmay be tightened or loosened as occasion may require'. The arm ofvthecrank projects from the shaft as far as the teeth of 'the plate, andis notched around' near the 'end of it, forming a hook, d, thereon. Thecrank below the shaft has a pin, e, (see iig. 2,) opposite to theperforationsin the plate. 'D is the paWl, supported cna small shaft,secured by a suitable bearing on the cross-pieceof the framing. It isconstructed with an arm, f, of sufeient gravity from its fulcrum tocounterbalance the opposite arm and thus keep it constantly in the teethof the plate luntil other wise moved therefrom. This arm has a pieceprojecting a little on theface side of the plate, having a catch, g.V

v Operation: When it is desired to raise the bucket, E, from the well,by taking hold of the handle of the crank and introducing the pin in oneof the perforations and turning the same, the plate is revolved and withit the Windlass. The outer part of the hole of the crank surrounding theshaft is chamfered ot?, and the back part of it slightly rounded,suiiciently to permit an easy lateral movement of the crank against theside of the plate, so that but little trouble will be experienced ininserting the pin in any of the perforations for turning the plate, aswell as the withdrawal of the same for the release of the pawl. When itis desired to lower the bucket, bybringing the crank around in either aforward or backward direction, whichever convenient, and pressing thehook of the arm of the'crank into the catch of the pawl, (see same inred lines in iig. 1,) either up 01 down, and by pressing Vthe armagainst the side 4of the plate at the same time, it acts as a brake,which, by a greater or less pressure, the bucket Amay be let down intothe Well slow or fast.

Having thus fully described our invention, what we claim therein as new,and desire to secure by Letters Patent, is- I f The crank (lasconstructed, with an arm and hook ot, in combination with the pawhcatehg and perforated plate A, substantially in the manner and for thepurpose as herein set forth.
